CNT-enhanced carbon electrode for nitrite detection and water analysis

Wendler, Frank / Aurosmit, Paul / Kanoun, Olfa

Abstract

In this contribution we present a novel electrode based on a bare pencil lead electrodes (PLEs) coated by carbon nanotubes. We investigate the sensitivity of the novel electrode during electrochemical analysis of aqueous solutions. For this purlose, a phosphate buffer having different nitrite concentrations has been subjected to meaurements with enhanced and bare PLEs over a wide potential range. The proposed coating increases the sensitivity to nitrite by increasing the electrode surface and its reactivity and shows therefore a significantly observable and sensitive signal.
